Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to an air inlet structure of an automobile air conditioner. Background Art

[0002] As the current trend of globalization continues to advance, it is a general trend for domestic automobile brands to go overseas. In order to meet the global market's left-hand and right-hand drive simultaneous development strategy, the use of a center-mounted design for car air conditioners has become the mainstream. However, center-mounted air conditioners have disadvantages such as large suction at the air inlet and high wind speed in large air volume and external circulation mode.

[0003] The rotating blower blades in a car's center air conditioner create air circulation. Outside air flows through the openings in the ventilation cover and into the body's gutter, ultimately entering the vehicle's air conditioning system through the air intake. To prevent water from falling from the car's windshield from entering the air conditioning intake, a water baffle is typically installed at the air conditioning intake. However, this baffle easily blocks the air flow path on the side of the air conditioning intake, reducing the effective air intake area. Therefore, while the air intake demand remains unchanged, the air intake velocity will increase, causing accumulated water in the body's gutter to be sucked into the vehicle's air conditioning system. This poses risks such as reduced filtration efficiency of the air conditioning filter, short circuits in the blower motor components within the air conditioning main unit, and abnormal noise from the rotating mechanism. Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides an automobile air-conditioning air inlet structure.

[0005] A car air-conditioning air inlet structure comprises: a front panel, on which an air inlet is provided; a water baffle, connected to the front panel and located on the upper side of the air inlet, a water guide groove being provided on the water baffle, and the water guide groove extending from one end to the other end in the length direction of the water baffle; a water flow trough sheet metal, located on the lower side of the water baffle, and a water flow trough constructed on the water flow trough sheet metal; wherein the water baffle comprises a main body, a first connecting part and a second connecting part, the first connecting part and the second connecting part are respectively connected to both sides of the main body in the horizontal direction, and at least a part of the first connecting part extends downward, and at least a part of the second connecting part extends in the horizontal direction, and the first connecting part and the second connecting part are both connected to the front panel.

[0006] With such arrangement, the water baffle is fixed in position by being connected to the front panel, and since it is located on the upper side of the air inlet, when the water flows from top to bottom due to the action of gravity, the water baffle can stop and carry the water flow, and the water guide groove extends from one end of the water baffle to the other end in the length direction, so that the water flow can flow out from both ends of the water baffle, thereby improving its ability to guide and drain the water flow. The water baffle is connected to the front panel by the first connecting part and the second connecting part, thereby improving its connection strength. At the same time, since the second connecting part extends in the horizontal direction, it will not stop the air flow on the horizontal side of the air inlet, thereby ensuring the air circulation area at the air inlet, thereby preventing the air flow rate at the air inlet from being too high and sucking the accumulated water at the water baffle and the water groove into the air conditioner.

[0007] In one embodiment, the water baffle has a flange on a side away from the front wall, and the flange extends upward.

[0008] In one embodiment, one end of the main body away from the front enclosure is recessed downward and connected to the flange, and the main body and the flange cooperate to form the water guide channel.

[0009] In one embodiment, the main body portion extends in a direction away from the front enclosure and is arranged at an angle to both the first connecting portion and the second connecting portion.

[0010] In one embodiment, a receiving groove is further provided on the main body, and the receiving groove is communicated with the water guide groove.

[0011] In one embodiment, the water guide channel includes a main body section, a first connecting section and a second connecting section, the first connecting section and the second connecting section are respectively connected to the two ends of the main body section, and the first connecting section and the second connecting section are lower than the main body section in the vertical direction.

[0012] In one embodiment, along a direction away from the front enclosure, a width of the end of the main body segment close to the first connecting segment is smaller than a width of the end of the main body segment close to the second connecting segment.

[0013] In one embodiment, a first connecting hole is provided on the first connecting portion, at least one first connecting member is passed through the first connecting hole, and the first connecting member is connected to the front enclosure; and / or a second connecting hole is provided on the second connecting portion, a second connecting member is passed through the second connecting hole, and the second connecting member is connected to the front enclosure.

[0014] In one embodiment, two first connection holes are formed on the first connection portion, the two first connection holes are arranged along a vertical direction, and the first connection member is passed through each of the two first connection holes.

[0015] A car comprises the car air-conditioning air inlet structure described above.

[0016] Compared with the existing technology, the utility model optimizes the structure of the water baffle so that although it can achieve a high-strength connection with the front panel through the two-part connecting structure of the first connecting part and the second connecting part, the second connecting part extends horizontally so that it will not affect the air intake from the side of the air inlet, thereby ensuring the area of ​​the air inlet to avoid the problem of accumulated water being sucked into the air conditioner due to excessive wind speed. It also improves the water guide groove structure corresponding to the second connecting part and expands its groove width, so that although the second connecting part extends horizontally, it still has a drainage effect balanced with the first connecting part.

[0026] The utility model provides an automobile air-conditioning air inlet structure 100, which has a water baffle 20 capable of stopping water from entering the air-conditioning air inlet, and the water baffle 20 has an avoidance structure to reduce its impact on the flow area of ​​the air-conditioning air inlet, thereby preventing the wind speed at the air inlet from being too high and the accumulated water from being sucked into the automobile air-conditioning interior.

[0027] See Figure 1-Figure 2The automobile air-conditioning air inlet structure 100 includes a front wall 10, a water baffle 20 and a water trough sheet metal 30. The front wall 10 is provided with an air inlet 11. The water baffle 20 is connected to the front wall 10 and is located on the upper side of the air inlet 11. A water guide groove 25 is provided on the water baffle 20, and the water guide groove 25 extends from one end to the other end in the length direction of the water baffle 20; the water trough sheet metal 30 is located on the lower side of the water baffle 20, and a water trough is constructed on the water trough sheet metal 30; wherein the water baffle 20 includes a main body 21, a first connecting part 22 and a second connecting part 23, the first connecting part 22 and the second connecting part 23 are respectively connected to both sides of the main body 21 in the horizontal direction, and at least a part of the first connecting part 22 extends downward, and at least a part of the second connecting part 23 extends in the horizontal direction, and the first connecting part 22 and the second connecting part 23 are both connected to the front wall 10. In this way, the water baffle 20 is fixed in position by being connected to the front panel 10, and since it is located on the upper side of the air inlet 11, when the water flows from top to bottom due to the action of gravity, the water baffle 20 can stop and carry the water flow. The water guide groove 25 extends from one end of the water baffle 20 in the length direction to the other end, so the water flow can flow out from both ends of the water baffle 20, thereby improving its ability to guide and drain the water flow. The water baffle 20 is connected to the front panel 10 through the first connecting part 22 and the second connecting part 23, thereby improving its connection strength. At the same time, since the second connecting part 23 extends in the horizontal direction, it will not block the air flow on the horizontal side of the air inlet 11, thereby ensuring the air circulation area at the air inlet 11, thereby preventing the air flow rate at the air inlet 11 from being too high and sucking the accumulated water at the water baffle 20 and the water trough into the air conditioner.

[0028] It needs to be explained that since the water baffle 20 is usually installed on the front panel 10, the front panel 10 is an important component of the car and is used in the assembly of the car. Therefore, the vertical direction of the front panel 10 and the above-mentioned water baffle 20 and water flow channel sheet metal 30 refers to the vertical direction of the car placed flat on the ground, that is, the direction of gravity, and the horizontal direction is the direction parallel to the ground.

[0029] The side of the water baffle 20 away from the front wall 10 has a flange 24, which extends upward. In this way, the flange 24 can stop the water from flowing forward. Compared with the stopping structure of the groove wall of a single water guide groove 25, the flange 24 has a better effect on blocking the water flow.

[0030] Furthermore, the end of the main body 21 facing away from the front panel 10 is recessed and connected to a flange 24. The main body 21 and flange 24 cooperate to form a water channel 25. This allows for a deeper channel 25, and the channel wall facing away from the front panel 10, due to the flange 24, provides better water flow blocking and guidance. Furthermore, this simplifies manufacturing, as the water channel 25 does not need to be separately formed, resulting in a simpler structure.

[0031] Of course, in other embodiments, the water guide groove 25 can also be directly opened on the main body 21 of the water baffle 20 and spaced apart from the flange 24, and is not limited to being directly formed by the flange 24 and the main body 21 as described above.

[0032] The main body 21 extends away from the front panel 10 and is angled relative to both the first connecting portion 22 and the second connecting portion 23. This extension of the main body 21 allows the water channel 25 and the flange 24 to be further horizontally spaced from the front panel 10. Consequently, as water flows downward, it preferentially impacts the main body 21 before flowing into the water channel 25. Any splashing water is also blocked by the water deflector 20 due to the horizontal extension of the main body 21, thereby reducing the amount of water that escapes the water deflector 20.

[0033] Preferably, see Figure 1 The main body 21 and the first connecting portion 22 and the second connecting portion 23 tend to be arranged vertically. The main body 21 extends in the horizontal direction, while the first connecting portion 22 and the second connecting portion 23 are connected to the front 10 in the vertical direction.

[0034] Furthermore, the main body 21 is provided with a receiving groove 211, which communicates with the water channel 25. This allows water in the water channel 25 to temporarily flow into the receiving groove 211 when the water flow is excessive for a short period of time. This improves the water retaining plate 20's ability to handle accumulated water. When excessive water flow occurs within a specific timeframe, the water retaining plate 20 can still guide the water and prevent it from overflowing. Furthermore, the receiving groove 211 can be positioned to align with other structures within the vehicle's front cabin, thereby avoiding interference with other structures.

[0035] The water channel 25 includes a main body section 253, a first connecting section 251, and a second connecting section 252. The first connecting section 251 and the second connecting section 252 are respectively connected to the two ends of the main body section 253. The first connecting section 251 and the second connecting section 252 are vertically lower than the main body section 253. This means that in the direction of gravity, the first connecting section 251 and the second connecting section 252 are positioned lower. Therefore, water on the main body section 253 naturally flows to the two ends and flows into the water channel in the water channel sheet metal 30 below, and is eventually discharged.

[0036] In order to improve the bearing capacity of the water retaining plate 20, the horizontal lengths of the main body 21 and the main body section 253 of the water guide groove 25 are greater than the first connecting portion 22, the second connecting portion 23 and the first connecting section 251 and the second connecting section 252 to improve the water retaining effect.

[0037] Along the direction away from the front panel 10, the width of the main body section 253 at the end closest to the first connecting section 251 is smaller than the width of the main body section 253 at the end closest to the second connecting section 252. Thus, since the first connecting section 251 corresponds to the first connecting portion 22 and the second connecting section 252 corresponds to the second connecting portion 23, and the first connecting portion 22 drains water vertically downward, while the second connecting portion 23 drains water horizontally, the first connecting portion 22 has a stronger drainage capacity due to the effect of gravity. In this case, the end of the main body section 253 leading to the second connecting section 252 is configured to be wider, meaning that more water flows to the second connecting portion 23, thereby increasing the water flow rate in the second connecting portion 23. This balances the poor drainage capacity of the second connecting portion 23 due to its horizontal extension, resulting in balanced drainage capacity at both ends of the water retaining plate 20 along its length.

[0038] The first connecting portion 22 has a first connecting hole, through which at least one first connecting member 221 is inserted, and the first connecting member 221 is connected to the front panel 10. Alternatively, the second connecting portion 23 has a second connecting hole, through which a second connecting member 231 is inserted, and the second connecting member 231 is connected to the front panel 10. In this way, the first connecting portion 22 is fixedly connected to the front panel 10 via the first connecting member 221, and the second connecting portion 23 is connected to the front panel 10 via the second connecting member 231. These two connection points enhance the connection strength between the water deflector 20 and the front panel 10.

[0039] The first connecting portion 22 is provided with two first connecting holes, which are arranged along the vertical direction, and each of the first connecting holes is penetrated by a first connecting member 221. Thus, the two first connecting members 221 are adapted to the vertically extending first connecting portion 22, further ensuring the structural strength of the water retaining plate 20.

[0040] The present invention also provides an automobile, comprising the automobile air-conditioning air inlet structure 100 as described above.

[0041] Compared with the prior art, the present invention optimizes the structure of the water baffle 20 so that although it is highly connected to the front panel 10 through the two-part connecting structure of the first connecting part 22 and the second connecting part 23, the second connecting part 23 extends horizontally so that it will not affect the air intake from the side of the air inlet 11, thereby ensuring the area of ​​the air inlet 11 to avoid the problem of accumulated water being sucked into the air conditioner due to excessive wind speed. The structure of the water guide groove 25 corresponding to the second connecting part 23 is also improved, and its groove width is expanded, so that although the second connecting part 23 extends horizontally, it still has a drainage effect balanced with the first connecting part 22.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
